Hi, can you please send me a sample .dae file exported from SketchUp (licu at quadsoftware.com). When I've exported groups of objects from 3ds max and XSI they've always appear as one single object in Grome. It may be that SketchUp saves the collada files in a different form.

Also what was the problem with the textures? I've saw that many exporters use complete absolute paths for images so you need to either keep the images in the initial location or manually edit the paths in .dae to point to the Grome libraries locations.

The problem is that the sketchup exporter exports the textures as texture00.jpg, texture01.jpg and so on. It assumes that you will load each modell separately.

However, Grome can only load one texture with the same name, and uses that one for every model that asks for texture01.jpg. This resulted in every model using the texturesof the first model I've placed.

This can be solved in two ways:

1. You put every model in the same scene, so the exporter gives a different number for every texture. This has the drawback that placing objects will be difficult in Grome, since the "center point" of the model will be far from the model itself.

2. After exporting, you manually edit the filenames of the textures, then replace the old ones with the new manually in the dae, with a text editor. This has the drawback that its boring as hell.

The problem with the way the SketchUp exported the dae file is that it creates multiple meshes inside the COLLADA and then instantiate one group with multiple instances in it. So you have multiple meshes in the file and each of them with one instance transformation to get it in the proper position relative to the others.

In Grome, DAE files are read as mesh files (resource files), instances are not read from them. Instances are created by user from the dae meshes (with Spawn or ObjectBrush tool). So this exporting approach would not work. You should find a way to collapse the meshes into one single mesh before exporting. A solution for this is pretty much application specific so you need to find a way specific to the way SketchUp exporter works. In Grome I just read the dae files and show the meshes from them. You should have the groups exporter into one single mesh with multiple materials.

To give you an example in 3DS Max, when you have a mesh made by multiple subparts (submaterials) and you export it you get one single mesh with multiple “triangle” sections in COLLADA for each submaterial. This kind of dae files is correctly shown in Grome as single meshes.
